After using these fans for over 3 months, I found that they perform as expected. One fan had a minor issue with working, but I realized it was clipped upside down and a simple flick of the blades fixed it. The other fan has been running almost constantly next to my bed and recently seemed to have a lack of airflow, but blowing directly into it fixed the problem. Overall, I feel like I have definitely gotten my money's worth from these fans.

After using the fan for about 4 weeks, I noticed that it wasn't producing any air. I had to dismantle it in order to try to repair it. It is now functioning properly, but I don't think it should have required fixing after just one month of use, especially since it is only used for 1-2 hours per day.
